Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Cerebrospinal fluid (CSF) flow oscillations have emerged as a potentially important marker related to brain clearance, but their acquisition often relies on specialized imaging MRI sequences. The purpose of this work was to enable quantitative assessment of CSF flow associated with cardiac, respiratory, and low‐frequency cycles using ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To validate a method to assess cardiac and respiratory brain pulsations in slowly sampled dynamic MR scans. Cardiac and respiratory pulsations are key drivers of neurofluid circulation. However, resolving their temporal dynamics requires fast imaging, which is not achievable in many dynamic MR acquisitions.

Fluid dynamics of cerebrospinal fluid flow in perivascular spaces [PDF]
Journal of the Royal Society Interface, 2019 The flow of cerebrospinal fluid along perivascular spaces (PVSs) is an important part of the brain’s system for delivering nutrients and eliminating metabolic waste products (such as amyloid-β); it also offers a pathway for the delivery of therapeutic drugs to the brain parenchyma.

Physiological Measurement, 2004
Hydrocephalus is far more complicated than a simple disorder of CSF circulation. Historically, it has been diagnosed using clinical and psychomotor assessment plus brain imaging. The role of physiological measurement to aid diagnosis becomes more appreciated in current clinical practice. This has been reflected by recently formulated guidelines for the

Cerebrospinal Fluid Dynamics in Megalencephaly
Developmental Medicine & Child Neurology, 1975SUMMARYMacrocephaly is one of the signs most commonly used in the diagnosis of hydrocephalus. Two children are reported who presented with macrocephaly. The results of neurological examination were normal apart from delay in mental development. Head circumferences were above the 98th percentile.

European Journal of Anaesthesiology, 2008
The pathophysiology of hydrocephalus can be modelled and described in terms of altered biomechanical parameters. Shunting is aimed to correct the patient's cerebrospinal fluid dynamics, compensating for inadequate cerebrospinal fluid re-absorption or insufficient volume buffering reserve.
